This manual is also suitable for

Thank you for choosing a JL Audio Stealthbox® for your automotive sound system.

With proper installation, your new vehicle-specific enclosed subwoofer system

will deliver years of listening pleasure.

We strongly recommend that you have your new Stealthbox® installed by your

authorized JL Audio dealer. The installation professionals employed by your

dealer have the necessary tools and experience to disassemble and reassemble

your vehicle properly. If you prefer to perform your own installation, please read

this installation guide completely before beginning the process.

If you choose to perform the installation yourself, it is absolutely

vital that the Stealthbox® be properly mounted to the vehicle

according to these instructions. Failure to mount the enclosure

properly presents two problems:

1) The sub-bass performance will suffer due to the movement of the

enclosure caused by the force exerted by the woofer(s).

2) A loose enclosure presents a serious safety hazard in the event of a

collision or sudden deceleration.

POWER RECOMMENDATION

JL Audio recommends high quality ampliers such as the JL Audio XD300/1v2. The diagram below shows the recommended crossover settings for the XD300/1v2. For a detailed description of the

amplier settings, consult the owner’s manual for the amplier. If another amplier is being used, please reference this illustration and use similar settings on that amplier.

CONNECTIONS

Using quality power, signal, and speaker wire is essential in ensuring the performance of your Stealthbox®. JL Audio recommends using a 4 AWG power kit such as the XD-PCS4-1B for your

Stealthbox® amplier. Other kits are available should you be using more than one amplier. Signal wire such as the JL Audio Premium Audio Interconnect Cables should be used to provide signal for

both channels of the amplier. JL Audio recommends using 12 AWG speaker wire for subwoofers such as our XC-BCS12-25.
